a 10 which the bottom or discharge doors ofver- -tical gesretorts are seated and closed, are ioxp'osed to conditions which cause them to twist, warp, bend or otherwise get out of position or place. he principal object of the resent invention is to provide a compact, e cient and reliable clamp or clam 'ng device which shall have. a sufiicient-ly wi e range of operation to insure roper engagement with the cotter- 120 or ike device'and which shall serve to expeditiously and'properly seal and tightly .010% the door.)

cotter-bar 1. Inasmu as the levers 10 and 11 and their connections are duplicii'tes'a de-. scription of. but one will be given as the other is just like it. A

l3 isv a shaft mounted in hearings 14c carried for example-by aportion' of'the door frame and provided wit-ha handle 15. Fast on this shaft isan eccentric 16 and also a two-part eccentricli'. The strap 18 of the .eccentric 1G is connected with thefree end of thelever 10 and the forked strap 19 of the two parts of the eccentric 17 is connected with the lever 10 intermediate of its ends. The eccentrics 1.6 and 17 are set it proper angular distances apart. ()n'the shaft 13 there is a fast colic-r20 provided with in 21 that-contact or collide with lugs 22 on the eccentric straps 19. Fixed as to the'door frame is a stop 23 with which a projection 28 on the eccentric strap 19 may collide.

In use the handle 15 is-turned and the lugs 21 and 22 collide and the eccentrics are turned so as to drop their straps. The result of this is that the link 12 is dropped or the fre e'iend of the moved away from the shaft 13 and the tion may vary considerably but the reae of the clamp is sufiiciently great for it to jget in I under the cotter-bar wit out fail. The hen dle 15 is turned so as to let the clamp, or more accurately, the link 12 swing in under the cotter-bar and the turning of the handle 15 and shaft 13 opcratesthe eccentrics and causes them one to push down the strap 18 and the other to pull up the strap 19 with the result that the cotter-bar is lifted so as to seat and tightly close the door.

In the modification shown in Figs. 6 to 8, the construction and operati n is the same, except that the eccentric 16 is somewhat peculiarly shaped in order to give a quick lift and a slow final clamping movement. As indicated in Fig. 6, 24 and 25 indicate position and in Fig. 6 the. parts are shown in unclamped position. The' eccentric 16% is struck from two centers and it therefore has a quick throw. The cams 26 and 27 attached respectively to the eccentric and strap arranged in a plane parallel to them serve to hold the parts in the position shown in Fig. 6 in case by reason of weight, the eccentric strap should tend to drop. When shifted 13 is turned-through 90 the parts are in the position shown in Fig. 7 andthe eccentric 16 has pushed its strap to the limit of its downward movement, while the eccentric 17 has caused comparatively little change in the position of its strap. s a result of this the lever 12 has been quickly lifted up into the position 24, thus the door is quickly lifted up to its seat. During the next 90 of revolution of the shaft 13 the eccentric or cam 16 produces no movement of its strap since its operative surface is concentric with the shaft l3",'but the eccentric 17* has lifted the link l2 from the position 24 to the position 25 slowly and the distance between 24 and 25 is short, so that the pressure necessary for tightening the door is applied slowly and therefore advantageously.

It will be obvious to those skilled in the art that modifications may bem'ade in details of construction and arrangement and hence the invention is not limited as to those matters, nor do I desire to limit my invention further than the state of the prior art may require. I

What I claim is:

1. A clamp for vertical gas retort doors comprising the combination of a rotatable operating shaft, a pair of cantalivers having their free ends adapted to operate on a part of the door, a pair of eccentrics on said shaft provided with strapsconnected to one and of said levers, and a lug on the shaft for turning the straps and levers, substantially as described.

2. A clamp for vertical gas retort doors comprising the combination of a rotatable operating shaft, 1 pair of cantalivers having their free ends adapted to operate on a part of the door, a pair of eccentrics on said shaft provided with straps connected to one of said levers, a lug on the shaft for turn' ing the traps and levers, and a fixed back stop for the straps and levers, substantially as described.

3. A clamp for vertical gas retort doors comprising the combination of a rotatable operating shaft, :1 pair of cantalivers, a link connecting the free ends of the cantalivers, a pair of eccentrics on. said shaft provided with straps connected to one of said levers, and a lug on the shaft for turning the straps and levers, substantially as described.

4. A clamp for Vertical gas retort doors comprising the combination of a cantaliver, an operating shaft, an eccentric on said shaft having a strap connected with the lever, and an eccentric on the shaft struck from two centers and provided with a strap for effecting a quick lift, substantially as described.

5. A clamp for vertical gas retort doors comprising the combination of an operating shaft, a cantaliver, an eccentric and strap connecting the lever and shaft, a second cccentric struck from two centers and ar-' rangcd on the shaft and provlded with a
